Service Description:

This Esri Landsat image service highlights the NDVI difference between 2000 and 2005. This NDVI difference is generated by subtracting the Landsat GLS 2005 NDVI images from Landsat GLS 2000 NDVI images. The resulting values in changed areas will show either an increase or decrease in spectral reflectance values, while the unchanged areas will be close to zero. The difference in spectral reflectance can then be related to change in land cover or use.

Time Enabled: Yes. (Start Time Field: GLS_START90_10; End Time Field: GLS_END90_10)

Data Source: This image service was compiled from Global Land Survey (GLS) datasets: 2000 and 2005. GLS datasets are created by the United States Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) using Landsat images. These global minimal-cloud cover, orthorectified Landsat data products support global assessments of land-cover, land cover-change, and ecosystem dynamics such as disturbance and vegetation health.
